Document Type and Number:
Japanese Patent JP7279641
Kind Code:
B2
Abstract:
Provided is a vertical crusher wherein the rod section of a pressing cylinder and a swing lever are connected, and the rod section is moved to the cylinder section side of the pressing cylinder to rotate the swing lever, thereby moving a crushing roller to the rotating table side and crushing, by means of the crushing roller, material loaded on the rotating table. The rod section of the pressing cylinder and the swing lever are connected through a connection section, and a helically wound spring is disposed between the cylinder section of the pressing cylinder and the connection section so as to be fitted over the rod section. The present invention enables, without the use of a complex control device and by the installation of the spring on the pressing cylinder which drives the swing lever, to reliably prevent the crushing roller from rapidly approaching the rotating table side.
